The public is investing billions of dollars in conservation easements, which now protect an estimated 40 million acres throughout the United States. But all is not well. Uncertainties in the law and abusive practices threaten to undermine public confidence in and the effectiveness of conservation easements as a land protection tool. This short article is part of a series of articles published in the law review discussing conservation easements, with a focus on what we have learned thus far and where we should go from here. This article sets the stage by describing the dramatic growth in the use of conservation easements, the various laws that impact easement creation and administration, a timeline of important legal and policy developments, and the recent surprising lack of certainty and consensus regarding what it means to protect land “in perpetuity” or “forever” with a conservation easement. The article concludes by discussing how the perpetuity issue might be productively resolved.
